This is for us so we can go in as the client and look at data that is being displayed for them.

We pass their address to a function to look at googlemap and name to look at linkedin profile. Wanted to do the same thing to look at their data in the dnn site. (We synch contacts, counts of activities, etc back and forth between dnn and telemagic)

Thought since the site is on the same box you might have an idea on how to do it securely.

If you say it shouldn't be done I believe you. My experience with you guys is you are very up on DNN.

We have similar functionality that we build into our modules. As an example, we have a license management tab: http://www.interactivewebs.com/Suppor...
that if you log in with an account that has the same email address as your license purchases, the module picks up on your history of module license purchases and activation, and will display your related data directly to you as a users.

We have the ability as administrators, to simulate via way or URL or email address, the details that a user would see when hitting that page. The idea is that we do not want to play "log in, log out" all the time, but we remain logged in as an admin, but stimulate the page and module to give us the same experience that a user would see.

Can I suggest that this approach may work for you. Rather than actually logging in and out all the time, just stay logged in as a user, and make the modules that display the data you see, have the ability to "simulate" a user, but way of user ID etc.
